A bit of advice...

[TrucknAndy]

I recently purchased a 72 GMC fleetside with a donated 86 chevy engine. The issue is I am not certain out of what. It would be much easier to get engine/tranny parts if I knew what it came out of so I could search the parts first based on actual information. I think I am going to answer my own question here, but would it behoove me to pull casting #'s off the engine, tranny, and heads? I dont know how stock the engine is which is why I mentioned the heads.

I am not certain how to search for parts based on the numbers, but I figure I could provide them to a parts store, and get what I need. The reason this came up is I have a minor leak. Originally thought the culprit was the valve cover gaskets. Only after the second trip, and bringing in the old gaskets did I get the right part. But, it seems now it is tranny fluid, and its either coming from the pan, or the shift linkage on the side of the case. Would be helpful to know what type of tranny I am dealing with to search for parts.

I am no mechanical brain child, but can figure things out pretty easily. However, I am feeling somewhat gimped, and hate not having info...makes you sound like an idiot when you're looking for parts, and advice.

Thanks,
Andy
